A nanecology built solely on inorganic nanobots. The most extreme form is Machinonanecology. In practice however most hylonanecologies and bionanecologies tend to merge, with each using components found in the other; the difference between them being one of degree rather than of kind.

Molecular Nanotechnology (dry nanotech). Use of artificially created non-biomolecular systems as replicators, assemblers, or components of molecular nanotechnology; any molecular nanotechnology not based on bio-molecules or biotech. Sometimes referred to as "Drexlerian nanotech".

- Nano-ecology, Nanecology - Text by Anders Sandberg
A distributed system of nanodevices and the structures constructed by them that self-organizes in a bottom-up manner without any central control; analogous to an ecology. Sometimes used to denote the entire nanosphere of a world, even when parts of it are under top-down control.
- Nanosphere - Text by M. Alan Kazlev
Generally, the part of a — usually nanoindustrialised or nanodeveloped — world (or more rarely habitat) that is pervaded or saturated by nanodevices — the realm of nano-interaction. Typical angelnets for example constitute a nanosphere.
